+**What it does**
+
+This tool joins two tabular files based on a common key column.
+
+-----
+
+**Example**
+
+**First file**::
+
+    Fruit	Color
+    Apple	red
+    Banana	yellow
+    Orange	orange
+    Melon	green
+
+**Second File**::
+
+    Fruit	Price
+    Orange	7
+    Avocado	8
+    Apple	4
+    Banana	3
+
+**Joining** both files, using **key column 1** and a **header line**, will return::
+
+    Fruit	Color	Price
+    Apple	red	4
+    Avocado	.	8
+    Banana	yellow	3
+    Melon	green	.
+    Orange	orange	7
+
+# Input files need not be sorted.
+# The header line (**Fruit  Color  Price**) was joined and kept as first line.
+# Missing values ( Avocado's color, missing from the first file ) are replaced with a period character.
